\ To a/ZZ whom, it may concern:

Be it known that I, PAUL BURCHARDT, a subject of the King of Swedenand'Norway, and a resident of Kramfors,in the Kingdom of Sweden, haveinvented certain new and -useful Improvements in Conveyers, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

' This invention relates to a conveyer especially adapted for theconveyance of different kinds of waste wood generally found in greatquantities in wood-mills. The ordinary conveyers, -consisting of aseries of boxes, shovels, or the like connected together to form a trainor belt, cannot be advantageously used, because the mass does not fallinto the boxes or shovels if the latter are not madeexceedingly large.Neither the ordinary conveyerbelts, consisting'of cotton fabric,india-rub? ber, leather, or the like, can be used for this purpose,because they are usually damaged by the mass, especially Whenthe latteris wet and full of twigs and other pointed pieces, in which case thebelt or band will often be in and reduce to a minimum the cost ofestablishing and maintaining the conveyer-arrangement, the conveyeriscomposed, according to this invention, of a simple vchute having plaininner sides on which the mass can easily glide and of an endless beltforming a movable bottom within the chute, said belt being built up ofsingle wide pieces of sheet metal, forming Fig. 4 shows a modification.

The wide pieces l of sheet metal are connected together lone with theother by hinges 2 to form an endless belt 3. Only a short portionthereof is shown in thedrawings, nor are the wheels or rollers shown.The latter can obviously be constructed in several ways.V For instance,they can be made of a pair of disks threaded on a shaft and connected.together by pegs or the like. The chute 4, in which I the belt ismoving, is suitably provided at the bottom with two or more longitudinalribs 5 5, of some hard kind of wood for the belt to glide upon. In orderto avoid wear, the side of the belt having projections formed by thehinges should beturned upward. In the modification shown in Fig. 4 thesheet-metal pieces are provided at one end with an anguvlar piece 6, sothat the belt as a whole will ,form a series of shovels.

This is necessary when the belt is to serve as an elevator; but it canalso beused when the beltmoveshorizontally.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a conveyer, the combination, with a chute having a bottom andlongitudinal ribs located within said chute and near the bottom thereof,of a belt consisting of a plurality of vfiat sheet-metal plates hingedtogether, said belt being movable longitudinally within said chuteV andbearing on said longitudinal ribs.

2. In a conveyer, the combination, with a chute having closed sides anda bottom, of longitudinal ribs carried by the sides of said chuteandnear the bottom, and a belt movable longitudinally within said chute andcomposed of a plurality of sheet-metal plates hinged t0- gether, eachplate being provided with an upturned integral portion forming Vanupwardextending shovel, said belt bearing on the lon'- gitudinal ribswithin the chute.

3. In a conveyer, the combination, with a PAUL EUECHAEDT.
